As a low time civilian applicant (1100hrs) at a regional, my interviewer was VERY interested in my military background, even though it was not aviation oriented. He was sharp enough to know that it demonstrated the ability to assimilate large amounts of technical info in a compressed, stressful period of time, which is exactly what 121 training is. I am convinced that it was a major factor in me getting the job, since my flying experience (CFI) was unremarkable.
